Choose the correct option. A rectangular coil of copper wires is rotated in a magnetic field. The direction of the induced current changes once in each
(1) two revolutions
(2) one revolution
(3) half revolution
(4) one-fourth revolution
solution:
The direction of induced current changes twice in one revolution i.e., it changes after every half revolution.
Thus,
option (3) is correct.
The direction of induced current changes twice in one revolution i.e., it changes after every half revolution.
Thus,
